Show me how gave the commands the audit runs: sed, awk and yq edits,
heredoc manifests, JSON patches, --overrides, sleeps and wait loops -
nothing anyone types in the exam. A step's show is now a list of
parts (sim/bank.py): cmd() is what you type as it stands; hand() is
what you do by hand - vim on a generated skeleton or on a manifest
pasted from the docs page it names, kubectl edit, ssh NODE and sudo
-i, a value you read and echo - with a script that does the same for
the audit. All 135 CKA steps are rewritten so, with k for kubectl;
their checks, titles and texts are unchanged.
Add ./ksim lesson lint, which reads what every step has you type and
flags scripts. The lesson audit runs it first.
Record the hosts whose setup failed when a session started. The page
warns above that task or lesson and offers Rebuild this host; the CLI
names ./ksim reset N on each step.
Render *italics* in lessons and tasks, outside code spans.
Audited on v1.37: CKA lessons 27/27, 135/135 steps, done the exam
way; lint clean. kubectl edit --subresource resize, the one edit the
audit replaces with a patch, was proven on its own.

Add runs of a domain's lessons: ./ksim lesson ARCH, the lobby's Teach
a domain card, or the Teach a domain session in the Start exam
dialog. A run is one lesson session over the domain's lessons not
done yet (--all: every one), each on its own host, all made before it
starts, so there is no waiting between lessons. The session keeps
the lesson you are on and each lesson's checks. A lesson's wrap-up
leads to the next, the list at the top of a lesson goes to any lesson
of the run, and ./ksim lesson next and ./ksim lesson OBJ do the same
in a terminal. Finishing the run sends you to the domain's drill.
Stamp a lesson done the moment its last step passes, not when the
session ends, so terminating a lesson or a run keeps what it taught.
Tested on a real STOR run in a copy of the repo: every host up before
step 1; lesson 1.1 done step by step through the CLI and the web API,
and stamped done as its last step passed; next, jump, a lesson
outside the run refused, and the finish report as expected.

Add lessons: untimed guided labs, one per curriculum objective, on a
host of their own, in the browser and in the terminal. Each step has
a check, a hint and its commands; a lesson writes no history or
scores, only a done mark on its objective. CKAD 2.1-2.4 (24 steps)
and all 27 CKA objectives (135 steps) have one, and `./ksim lesson
audit` proves that every step fails, is done by its own commands,
then passes.
Add CKA tasks 132-147 (cka/bank_course.py) on what a full CKA course
teaches beyond the bank: a real upgrade from v1.36, a drain under a
PodDisruptionBudget, QoS and eviction, in-place resize, kube-proxy's
chains, encryption at rest, an operator, and CSI expansion, snapshots
and clones (ensure_csi_hostpath).
Move CKA and CKS to Kubernetes v1.37 and rebuild the hosts on Ubuntu
24.04, with kubelet, kubeadm and kubectl as held packages from
pkgs.k8s.io; the desktop runs Ubuntu too. Hosts gain man pages,
hexdump and xxd.
Fix CKS Q4, which gave 3 of 12 points untouched, and CKA Q4 and Q49,
whose solutions raced their new CRD.
Audited on v1.37: CKA 147/147, CKAD 105/105, CKS 109/110 (Q103, a
Falco task, failed to seed once and awaits a re-audit); lessons: 135
of 135 CKA steps and 24 of 24 CKAD steps.
